DISEASES AND TREATMENT OF THE HORSE 105 



in some cases is of a yellowish color. In order to tell whether 

 the sinuses are much affected tap on the bone over the 

 sinuses with the finger; if this makes a dull sound as if the 

 sinuses were full, you may conclude that they are diseased ; 

 but if a hollow drum-like sound, you may come to the con- 

 clusion that the sinuses are not much affected and there is 

 more hope of recovery. As the disease continues, the animal 

 becomes very much weaker; the discharge has a very bad 

 smell, showing that the bones of the head are becoming af- 

 fected. If a bad tooth is causing the trouble, the discharge 

 comes only from one nostril. He will not eat very well ; 

 sometimes, after taking a bite, he will throw the food out of 

 his mouth. The breath has a very bad smell and the horse 

 will soon run down in condition. To distinguish this disease 

 from glanders, notice first, that the discharge in glanders is 

 of a greenish color and will sink in water, while the discharge 

 in nasal gleet will float on water; second, the lining inside 

 of the nose, if the animal has glanders, will be covered with 

 small ulcers. Again, the temperature in suffering from nasal 

 gleet will be about normal, but if from glanders will run as 

 high as 103° or 105°. In doubtful cases you might even 

 apply the Mallein Test, fully described in Chapter XV. 



Treatment. — This disease is not, as a general thing, 

 easily treated. If the animal is thin and run down in condi- 

 tion, it is well to build him up with good food, regular exer- 

 cise, pure air and the following mixture: 



Ground Sulphate of Iron Ys, pound. 



Ground Sulphate of Copper % pound. 



Ground Gentian Root ]4 pound. 



. Mix thoroughly and give a teaspoonful twice a day, night 

 and morning, on his tongue or in his feed. Wash the nostrils 

 twice a day with warm water. If you conclude that the 

 sinuses are much affected or that some food or foreign sub- 

 stance is causing the trouble, the treatment will then be dif- 

 ferent. The animal should be thrown and secured with a 

 rope. Strip a piece of skin about an inch in diameter from 

 the bone with a knife and with a trephine bore a hole through 

 the bone into the sinuses. This is easily done, the bone at 

 this point being thin and soft. Little pain is caused and but 

 little risk of danger is run. See fig. 3. When the hole is 

 made the pus will discharge and with it generally comes the 

 cause of the trouble. Make the hole as near the lower part 

 of the sinus as possible so as to allow the discharge all to
